"The Congress!" he said. "Fifteen men and women--counting me. Self-appointed and helpless."

"You didn't think so when you were a member."

"I've grown older. I've learned,"

"At least you've learned to betray your friends."

"There was no betrayal. Hines tried to damage Multivac; a foolish, impossible thing for him to try."

"You accused him."

"I had to. Multivac knew the facts without my accusation, and without my accusation, I would have been an accessory. Hines would not have gained, but I would have lost."

"Without a human witness, Multivac would have suspended sentence,"

"Not in the case of an anti-Multivac act. This wasn't a case of illegal parenthood or life--work without permission. I couldn't take the chance."

"So you let Simon be deprived of all work permits for two years,"

"He deserved it."

"A consoling thought, You may have lost the confidence of the Congress, but you have gained the confidence of Multivac," consoling thought, You may have lost the confidence of the Congress, but you have gained the confidence of Multivac,"

"The confidence of Multivac is important in the world as it is, " said Bakst seriously. He was suddenly conscious of not being as tall as Noreen, She looked angry enough to strike him; her lips pressed whitely together, But then she had pa.s.sed her eightieth birthday-no longer young-the habit of non-violence was too ingrained. ...Except for fools like Hines.

"Is that all you have to say, then?" she said.

"There could be a great deal to say, Have you forgotten? Have you all forgotten? Do you remember how it once was? Do you remember the Twentieth Century? We live long now; we live securely now; we live happily now."

"We live worthlessly now."

"Do you want to go back to what the world was like once?"

Noreen shook her head violently. "Demon tales to frighten us. We have learned our lesson. With the help of Multivac we have come through--but we don't need that help any longer. Further help will soften us to death. Without Multivac, we we will run the robots, will run the robots, we we will direct the farms and mines and factories." will direct the farms and mines and factories."

"How well?"

"Well enough. Better, with practice. We need the stimulation of it in any case or we will all die."

Bakst said, "We have our work, Noreen; whatever work we choose."

"Whatever we choose, as long as it's unimportant, and even that can be taken away at will-as with Hines. And what's your work, Ron? Mathematical games? Drawing lines on paper? Choosing number combinations?"

Bakst's hand reached out to her, almost pleadingly. "That can be important. It is not nonsense. Don't underestimate--" He paused, yearning to explain but not quite knowing how he could, safely. He said, "I'm working on some deep problems in combinatorial a.n.a.lysis based on gene patterns that can be used to--"

"To amuse you and a few others. Yes, I've heard you talk about your games. You will decide how to move from A to B in a minimum number of steps and that will teach you how to go from womb to grave in a minimum number of risks and we will all thank Multivac as we do so."

She stood up. "Ron, you will be tried. I'm sure of it. Our Our trial. And you will be dropped. Multivac will protect you against physical harm, but you know it will not force us to see you, speak to you, or have anything to do with you. You will find that without the stimulation of human interaction, you will not be able to think--or to play your games. Goodbye." trial. And you will be dropped. Multivac will protect you against physical harm, but you know it will not force us to see you, speak to you, or have anything to do with you. You will find that without the stimulation of human interaction, you will not be able to think--or to play your games. Goodbye."

"Noreen! Wait!"

She turned at the door. "Of course, you will have Multivac. You can talk to Multivac, Ron."

He watched her dwindle as she walked down the road through the parklands kept green, and ecologically healthy, by the un.o.btrusive labors of quiet, single-minded robots one scarcely ever saw.

He thought: Yes, I will have to talk to Multivac.

Multivac had no particular home any longer. It was a global presence knit together by wire, optical fiber, and microwave. It had a brain divided into a hundred subsidiaries but acting as one. It had its outlets everywhere and no human being of the five million was far from one.

There was time for all of them, since Multivac could speak to all individually at the same time and not lift its mind from the greater problems that concerned it.

Bakst had no illusions as to its strength. What was its incredible intricacy but a mathematical game that Bakst had come to understand over a decade ago? He knew the manner in which the connecting links ran from continent to continent in a huge network whose a.n.a.lysis could form the basis of a fascinating game. How do you arrange the network so that the flow of information never jams? How do you arrange the switching points? Prove that no matter what the arrangement, there is always at least one point which, on disconnection Once Bakst had learned the game, he had dropped out of the Congress. What could they do but talk and of what use was that? Multivac indifferently permitted talk of any kind and in any depth precisely because it was unimportant. It was only acts that Multivac prevented, diverted, or punished.

And it was Hines's act that was bringing on the crisis; and before Bakst was ready for it, too.

Bakst had to hasten now, and he applied for an interview with Multivac without any degree of confidence in the outcome.

Questions could be asked of Multivac at any time. There were nearly a million outlets of the type that had withstood Hines's sudden attack into which, or near which, one could speak. Multivac would answer.

An interview interview was another matter. It required time; it required privacy; most of all it required Multivac's judgment that it was necessary. Although Multivac had capacities that not all the world's problems consumed, it had grown chary, somehow, of its time. Perhaps that was the result of its ever-continuing self-improvement. It was becoming constantly more aware of its own worth and less likely to bear trivialities with patience. was another matter. It required time; it required privacy; most of all it required Multivac's judgment that it was necessary. Although Multivac had capacities that not all the world's problems consumed, it had grown chary, somehow, of its time. Perhaps that was the result of its ever-continuing self-improvement. It was becoming constantly more aware of its own worth and less likely to bear trivialities with patience.

Bakst had to depend on Multivac's good will. His leaving of the Congress, all his actions since, even the bearing of evidence against Mines, had been to gain that good will. Surely it was the key to success in this world.

He would have to a.s.sume the good will. Having made the application, he at once traveled to the nearest substation by air. Nor did he merely send his image. He wanted to be there in person; somehow he felt his contact with Multivac would be closer in that way.

The room was almost as it might be if there were to be a human conference planned over closed multivision. For one flash-by moment, Bakst thought Multivac might a.s.sume an imaged human form and join him-the brain made flesh.

It did not, of course. There was the soft, whispering chuckle of Multivac's unceasing operations; something always and forever present in Multivac's presence; and over it, now, Multivac's voice.

It was not the usual voice of Multivac. It was a still, small voice, beautiful and insinuating, almost in his ear.

"Good day, Bakst. You are welcome. Your fellow human beings disapprove of you."

Multivac always comes to the point, thought Bakst. He said, "It does not matter, Multivac. What counts is that I accept your decisions as for the good of the human species. You were designed to do so in the primitive versions of yourself and--"

"And my self-designs have continued this basic approach. If you you understand this, why understand this, why do do so many human beings fail to understand it? I have not yet completed the a.n.a.lysis of that phenomenon." so many human beings fail to understand it? I have not yet completed the a.n.a.lysis of that phenomenon."

"I have come to you with a problem," said Bakst. Multivac said, "What is it?"

Bakst said, "I have spent a great deal of time on mathematical problems inspired by the study of genes and their combinations. I cannot find the necessary answers and home computerization is of no help."

There was an odd clicking and Bakst could not repress a slight shiver at the sudden thought that Multivac might be avoiding a laugh. It was a touch of the human beyond what even he was ready to accept. The voice was in his other ear and Multivac said: "There are thousands of different genes in the human cell. Each gene has an average of perhaps fifty variations in existence and uncounted numbers that have never been in existence. If we were to attempt to calculate all possible combinations, the mere listing of them at my fastest speed, if steadily continued, would, in the longest possible lifetime of the Universe, achieve but an infinitesimal fraction of the total."

Bakst said, "A complete listing is is not needed. That is the point of my game. Some combinations are more probable than others and by building probability upon probability, we can cut the task enormously. It is the manner of achieving this building of probability upon probability that I ask you to help me with." not needed. That is the point of my game. Some combinations are more probable than others and by building probability upon probability, we can cut the task enormously. It is the manner of achieving this building of probability upon probability that I ask you to help me with."

"It would still take a great deal of my time. How could I justify this to myself?"

Bakst hesitated. No use in trying a complicated selling job. With Multivac, a straight line was the shortest distance between two points. .

He said, "An appropriate gene combination might produce a human being more content to leave decisions to you, more willing to believe in your resolve to make men happy, more anxious to be be happy. I cannot find the proper combination, but you might, and with guided genetic engineering--" happy. I cannot find the proper combination, but you might, and with guided genetic engineering--"

"I see what you mean. It is-good. I will devote some time to it."

Bakst found it difficult to hitch into Noreen's private wave. length. Three times the connection broke away. He was not surprised. In the last two months, there had been an increasing tendency for technology to slip in minor ways-never for long, never seriously-and he greeted each occasion with a somber pleasure.

This time it held. Noreen's face showed, holographically three-dimensional. It flickered a moment, but it held.

"I'm returning your call," said Bakst, dully impersonal.

"For a while it seemed impossible to get you," said Noreen. "Where have you been?"

"Not hiding. I'm here, in Denver."

"Why in Denver?"

"The world is my oyster, Noreen. I may go where I please."

Her face twitched a little. "And perhaps find it empty everywhere. We are going to try you, Ron."

"Now?"

"Now!"

"And here?"

"And here!"

Volumes of s.p.a.ce flickered into different glitters on either side of Noreen, and further away, and behind. Bakst looked from side to side, counting. There were fourteen, six men, eight women. He knew every one of them. They had been good friends once, not so long ago.

To either side and beyond the simulacra was the wild background of Colorado on a pleasant summer day that was heading toward its end. There had been a city here once named Denver. The site still bore the name though it had been cleared, as most of the city sites had been. ...He could count ten robots in sight, doing whatever it was robots did.

They were maintaining the ecology, he supposed. He knew no details, but Multivac did, and it kepi fifty million robots allover the Earth in efficient order.

Behind Bakst was one of the converging grids of Multivac, almost like a small fortress of self-defense.

"Why now?" he asked. "And why here?"

Automatically he turned to Eldred. She was the oldest of them and the one with authority-if a human being could be said to have authority.

Eldred's dark-brown face looked a little weary. The years showed, all six score of them, but her voice was firm and incisive. "Because we have the final fact now. Let Noreen tell you. She knows you best."

Bakst's eyes shifted to Noreen. "Of what crime am I accused?"

"Let us play no games, Ron. There are no crimes under Multivac except to strike for freedom and it is your human crime that you have committed no crime under Multivac. For that we will judge whether any human being alive wants your company any longer, wants to hear your voice, be aware of your presence, or respond to you in any way."

"Why am I threatened with isolation then?"

"You have betrayed all human beings."

"How?"

"Do you deny that you seek to breed mankind into subservience to Multivac?"

"Ah!" Bakst folded his arms across his chest. "You found out quickly, but then you had only to ask Multivac."

Noreen said, "Do you deny that you asked for help in the genetic engineering of a strain of humanity designed to accept slavery under Multivac without question?"

"I suggested the breeding of a more contented humanity. Is this a betrayal?"

Eldred intervened. She said, "We don't want your sophistry, Ron. We know it by heart. Don't tell us once again that Multivac cannot be withstood, that there is no use in struggling, that we have gained security. What you call security, the rest of us call slavery."

Bakst said, "Do you proceed now to judgment, or am I allowed a defense?"

"You heard Eldred," said Noreen. "We know your defense." .

"We all heard Eldred," said Bakst, "but no one has heard me. What she says is my defense is not my defense."

There was a silence as the images glanced right and left at each other. Eldred said, "Speak!"

Bakst said, "I asked Multivac to help me solve a problem in the field of mathematical games. To gain his interest, I pointed out that it was modeled on gene combinations and that a solution might help in designing a gene combination that would leave man no worse off than he is now in any respect and yet breed into him a cheerful acceptance of Multivac's direction, and acquiescence in his decisions."

"So we have said," said Eldred.

"It was only on those terms that Multivac would have accepted the task. Such a new breed is clearly desirable for mankind by Multivac's standards, and by Multivac's standards he must labor toward it: And the desirability of the end will lure him on to examine greater and greater complications of a problem whose endlessness is beyond what even he can handle. You all witness that."

Noreen said, "Witness what?"

"Haven't you had trouble reaching me? In the last two months, hasn't each of you noticed small troubles in what has always gone smoothly? ...You are silent. May I accept that as an affirmative?"

"If so what then?"

Bakst said, "Multivac has been placing all his spare circuits on the problem. He has been slowly pushing the running of the world toward rather a skimpy minimum of his efforts, since nothing, by his own sense of ethics, must stand in the way of human happiness and there can be no greater increase in that happiness than to accept Multivac."

Noreen said, "What does all this mean? There is still enough in Multivac to run the world-and us-and if this is done at less than full efficiency, that would only add temporary discomfort to our slavery. Only temporary, because it won't last long. Sooner or later, Multivac will decide the problem is insoluble, or will solve it, and in either case, his distraction will end. In the latter case, slavery will become permanent and irrevocable."

"But for now he is distracted," said Bakst, "and we can even talk like this-most dangerously-without his noticing. Yet I dare not risk doing so for long, so please understand me quickly.

"I have another mathematical game-the setting up of networks on the model of Multivac. I have been able to demonstrate that no matter how complicated and redundant the network is, there must be at least one place into which all the currents can funnel under particular circ.u.mstances. There will always be the fatal apoplectic stroke if that one place is interefered with, since it will induce overloading elsewhere which will break down and induce overloading elsewhere--and so on indefinitely till all breaks down."

"Well?"

"And this is the point. Why else have I come to Denver? And Multivac knows it, too, and this point is guarded electronically and robotically to the extent that it cannot be penetrated."

"Well?"

"But Multivac is distracted, and Multivac trusts me. I have labored hard to gain that trust, at the cost of losing all of you, since only with trust is there the possibility of betrayal. If any of you tried to approach this point, Multivac might rouse himself even out of his present distraction. If Multivac were not distracted, he would not allow even me to approach. But he is is distracted, and it distracted, and it is is I!" I!"

Bakst was moving toward the converging grid in a calm saunter, and the fourteen images, keyed to him, moved along as well. The soft susurrations of a busy Multivac center were all about them.
